## Modules

SharedID: We need you to include the [SharedID module](/dev-docs/modules/userid-submodules/sharedid.html) in order to bid effectively on your inventory.

### Registration

The preciso Bidding adapter requires setup before beginning. Please contact us at [tech@preciso.net]

Notes:

- It is best to provide the `bidfloor` in priceFloor module.

- Preferred to provide the `bcat` and `badv` within the first party data (above). When both methods are provided, first party data values will be prioritized.
